84.87 Machinery parts, not containing electrical connectors, insulators, coils, contacts or other electrical features, not specified or included elsewhere in this Chapter.
This heading covers all non-electrical parts of machinery, other than :(a) Those specially designed for use solely or principally with a particular machine (including a machine of heading 84.79 or 85.43, of Section XVII, Chapter 90, etc.) and therefore classified in the same heading as that particular machine (or, where a separate heading is provided, in that separate heading). (b) Parts covered by heading 84.81 to 84.84. (c) Parts covered more specifically by other headings of the Nomenclature or excluded by Note 1 to Section XVI or Note 1 to Chapter 84, for example, transmission or conveyor belts or belting, of plastics (Chapter 39); transmission or conveyor belts or belting, of vulcanised rubber (heading 40.10), and other parts made of unhardened vulcanised rubber (heading 40.16); parts made of leather or of composition leather (heading 42.05); transmission or conveyor belts or belting, of textile material (heading 59.10), and other machinery parts made of textile material (heading 59.11); parts made of ceramics or of glass (Chapter 69 or 70); machinery parts made wholly of precious or semi precious stones (natural, synthetic or reconstructed) (Chapter 71); screws, chains, springs and other parts of general use as defined in Note 2 to Section XV; brushes (heading 96.03). In general, therefore, the goods of this heading are such as can be recognised as being parts of machines, but not as parts of any particular machine. Subject to these conditions, the heading includes non-automatic lubricating pots; greasing nipples; hand wheels, levers and hand grips; safety guards and baseplates; and oil seal rings. These rings, which are generally of circular cross-section, have a fairly simple structure (a flexible rubber ring and a metal reinforcement assembled by vulcanisation, for example), characterised by the absence of movable parts. They are used in a large number of machines or apparatus to prevent leaks of oil or gas or to prevent dust, etc., from entering, by sealing the surfaces to be joined. The heading also covers propellers and paddle-wheels for ships or boats.
